To all whom it may concern:

Be it known that I, FRANKLIN E. ABBOTT, a citizen of the United States,residing at Buffalo, in the county of Erie and State of I New York, haveinvented new and useful Improvements in Tie Plates, of whichthefollowing is a specification.

' My invention relates to tie-plates for railways characterized by ahook-shoulder arranged to engage with the rail-flange and consists inproviding a second shoulder for engaging with the opposite rail flange.

I have heretofore invented an improvement in hook-shoulder tie-plates.which consists in forming and proportioning the hookshoulder so thatits overhang shall be spaced a small distance from the upper surface ofthe rail flange, whereby the great security of the hook fastening isobtained without objectionable rigidity, and freedom of wave motion ispermitted, with greatly reduced disturbance of the spikes and of theroadbed. Tie-plates provided with my peculiar 1 hook-shoulder and withanordinary straight shoulder for engaging with the opposite rail flangehave gone largely into use of late, particularly for difficultlocations, where security in the rail fastenings is important andaccident would have serious consequences. I believe such tie plate to benew and I have broadly claimed the same in my application which resultedin Patent No. 1,178,200, Apr. 4, 1916.

My present invention consists in a tie-' plate whereby much greatersecurity is obtained, and this is accomplished by provid ing thetie-plate with two: hook-shoulders, one integral as before, and theother consisting of an integral shoulder without a hook and of adetachable hook, or clip, fitted to the second shoulder and secured inposition thereon. Both shoulders are spaced from the flange.

My invention is fully shown in the drawing herewith in which thereference numerals of this description are used to indicate thecorresponding parts in all the views.

Figs. 1 and 2 show in plan and side elevation a desirable form oftie-plate embodying my present invention. Figs. 3 and 4 arecorresponding views of the clip or detachable hook portion. Figs. 5 and6 show the tieplate applied respectively to wooden and to to receive andfirmly to sustain the clip so that the clip-hook may operate to engagewith.the rail base on the side opposite theintegral shoulder andcooperate with the latter to retain the rail in place with greatsecurity. To that end the second, or straight, shoulder may be. of anydesired form that w ll firmly engage with the groovein the clip, butpreferably as here shown substantially of dove-tail construction, havingone or more upper flanges or enlargements 7, so

that the upper part is wider than the neck. The particular form hereshown of outwardly and upwardly curved flanges is desirable for suchshape of shoulder is-easy to roll and requires the minimum of metal.'The clip 4 is correspondingly formed with claws 11 forming a groove 12substantially to fit the dove-tail shoulder, both the shoulder and clipbeing of uniform size from end to end so that the clip fits the shouldersnugly, but yet may easily be slipped into place thereon after the railhas been set in position on the bed 14 between the two shoulders.

The rail is ,then firmly and positively secured in place by the twohooks, of which the c lip.-hook is maintained firmly in place by 1t speculiarl formed shoulder against all possibility of displacement byany'fo-rce that may be exerted thereon by the rail. And by contact withthe rail and therefore are not disturbed or loosened by direct strainthereonof the rail during the wave motion, and, owing to the spacebetween the hooks and the rail flanges, the indirect effect of thewavemotion on the spikes is trifling.

There exists however the possibility of the clip slipping off graduallyand longitudinally due to vibration. To counteract this some retainingmeans must be provided such as the spike 16 through the spike holes '17and inclip and shoulder as shown in Fig. 5 and Figs. 1 and 3, or thespecial bolt 18 p I and nut of Fig. 6.

The edges of the tie-plate outside of the shoulder may be made thinnerand lighter 'to save metal, but the center heavier and thicker to resistthe stresses and to afford a good bed for the rail. The tie-plates arepreferably balanced, that is of'equal width on each side of the centrallongitudinal 'axis of the rail-bed to permit reversal and convenienthandling. The plates may be longer for wooden ties and shorter formetal.

My tie-plate is equally well adapted to botlf wooden andmetal ties. InFig. 5 the tie-plate is shown in use with wooden ties, secured in placeby driven spikes or screw spikes, 22, the latter form of spike beinindicated. To carry out the best plan of installing the tie-plates onwooden ties, places of plate bearing should be formed at both ends ofthe tie, even and flat and exactly in the same plane. When screw spikesare used,

. it is also desirable and economical to bore holes in the tie thereforand .to fasten the plates to the .ties in the shop by machines. In Fig.6 the tie plate is shown secured to a metal tie by bolts or rivets 23;this as.- sembling'may} also be more conveniently done at the factorythan in the field. The ties whether wood or metal, thus fitted with thetie-plates, are then carried-to the place of use, Wherethey' are placedin the roadbed, the .rails then set in position and "se-- curelyfastened to the tie-plates and the ties by putting the clips in place onthe clip shoulders. v

Furthermore my new tie-plate permits the 'convenient replacing of tieswith'the track in position: A single tie may beremoved, and a new onewith the tie-plates attached easily be substituted, for there issufficient, space between the two shoulders to permit the rail to be setin position on the tieplates and,then the integral hooks adjusted toengage with both rails. The clips are then easily put in place on theirshoulders and there fastened, completing the holding arrangement. I

It will be understood that I intend to leave a clear space of sufficientsize betweeneach hook and the rail-base to permit the free Wave motionas above described and not so large but that at each upward movement ofthe rail it will engage with the hook to be held down. in place andprevented from upsetting. A space of from 9; to about inch isrecommended, not above about. inch. My present invention is not limitedto such space, but the tie-plate here described and claimed may be usedwith a space .under one hook, orunder both, or

under neither, that is the hooks may fit the flanges tight if anyonewishes so to use them,

Without departing from my present invention.

Nor do I propose to limit myself to having one 11001501 the other: onthe inside but either; the integral .or detachable hook may be arrangedinside or out as mostconvenient.

I so calculate the metal that the clip hook is substantially as strong'as the integral,

'or 1n part, or certain parts bent. to shape more or less by forgingorbull-dozing. The integral shoulders may extend the full length of thetie-plates and the hooks thereon extend from end to end of the shoulderas described in my said application but I prefer to make said hooksshorter as here shown.

The clip-shoulders and clips may also beequal in length to the length'ofthe tie-plate, and it is preferred to so form the. clipshoulders, butthe clip hooks may :be shorter and preferably substantiallyequal inlength and extent of engagement with the rail flange to theintegralhooks, when they are short.' a
